NEW DELHI: In a major development to the probe of the alleged gangrape and hanging of two cousins, the Central Bureau of Investigation (CBI) has decided to conduct a polygraph or lie-detector test on the fathers of the victims.
Sources said the statements given by the family members had several inconsistencies, which needed to be clarified for further probe.
Four persons, including the fathers of the two cousins and two other family members, will undergo the test, for which their consent has already been taken.
“The CBI will move the court seeking its permission to conduct the lie-detector test. The agency does not doubt the claims made by the family members, but to ensure foolproof investigation, it has to clarify certain inconsistencies. Though it is not admissible as evidence, it will at least help the agency in zeroing on certain leads,” sources added.
Earlier, A L Banerjee, Director General of Police, Uttar Pradesh, had indicated that there could be other motives in the case, and added that forensic experts had ruled out rape in the case of one girl.
